Voltaix, headquartered in Branchburg, N.J., was the former ChemOvonic division of Energy Conversion Devices, from which it was spun off in 1986. The company plans to use this funding to build out its business to sell into the growing thin-film solar industry and sees particular potential in the realm of building integrated photovoltaics. However, not all thin-film manufacturing require Voltaix’s chemical products, and startups are working on printing systems that don’t require vacuum chambers or dangerous gases to achieve even and cheap deposition.
